Q:Ductile iron pipes perennial bubbles in the water will rot it
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:What is the content of silicon in silicon molybdenum ductile iron?
High silicon molybdenum ductile cast iron is developed for end users successfully reduces the cost, and the castings have high strength, good oxidation resistance, and has good performance under thermal cycling condition. This kind of ductile iron silicon content of 4% molybdenum content 0.6%-0.8%, currently designated as many car manifold and turbocharger shell, and molybdenum content than the silicon alloy casting 1% more for special high temperature exhaust pipe, heat treatment. High silicon molybdenum alloy nodular cast iron castings used in the production of automotive turbocharger.
Q:Water supply pipe is ductile iron, then it's fittings and valves and other parts must be ductile iron?
Valve parts and materials do not require the same pipe material, as long as it can meet the use requirements and cost-effective.
Q:The difference between HDPE pipe and ductile iron pipe
Different appearance, ductile iron pipe single length of 6 meters, large wall thickness; mechanism cast iron pipe single length of 3 meters, the wall thickness is thin.
Q:If the ductile iron pipe is broken, can we use rush repair?
In this way, manpower, material resources and financial resources can be saved, time can be saved, and unnecessary troubles to the citizens' water supply can also be reduced.
Q:Ductile iron pipe in the direction of it?
The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Ductile iron is good, its tensile properties are destined to withstand low temperatures, gray cast iron is a little bit worse.
Q:What's the function of the cement mortar lining of ductile iron pipes?
In brief, the cement mortar lining system has the following advantages:1. provide active protection better than barrier coating2. meet both national and international standards for contact with potable water3. can be used in the strict requirements of the occasion4. strong and shock resistant5. suitable for a wide range of applications6. easy to repair7. over 100 years of service life
Q:How to properly maintain FRP pipes
Light weightThe weight of the pipe is only 1/4 of the same size and the same length as the ductile iron pipe, and 1/10 of the cement pipe. The transportation is easy to handle and easy to install.
Q:Ductile iron gears are generally treated without heat treatment
Heat treatment must be necessary, generally annealed first to machine, after quenching or nitriding treatment
